When the flow rate is monitored with a flow meter and temperature differential with two temperature gauges; it is easy to calculate how much energy your system is producing.

The most popular flow meter we offer is the 0.5-4 GPM range. This is the range that will be supplied unless otherwise specified.

The flow meter is avalible in many additional flow rate ranges. Select the smallest meter that includes your highest flow rate. Smaller ranges are more can measure your flow with higher accuracy. Please specify in the customer comments section on checkout if you prefer one of these other ranges.
